This is my second Giro Pneumo helmet. My first was a gift several years ago, and it quickly became my favorite of all I have tried -- mostly a matter of comfort -- fit and ventilation. I like the style as well, but that is not really too much a factor for me.

A couple of years ago, I crashed hard (got caught out after sundown when a ride took longer than planned) and hit an unseen pothole. I landed about 15 feet beyond the hole, striking the top of my head and then landing on my back. The top and rear of the helmet took a real hit, with the foam liner doing exactly what it was intended to do -- was out for at least a few moments, but suffered no ill effects.

I have used several other helmets since then, but finally broke down and purchased another Pneumo and could not be happier with it. I hope I do not soon crash test this one!

I read previous reviews that suggested it ran small, so ordered a large. My previous Bell helmet was a M/L. Had to send it back for a medium, which fits perfectly. I like the easily adjustable RocLoc. This is the most comfortable helmet I've owned. Ventilation seems very good. My wife says it looks nice. Hasn't made me a faster rider, though.

This is my 2nd Pneumo. I don't want to spend a whole lot on a helmet so the thing I like best about this is the quality for the price. I spent less than $100 thanks to a sale.I have a long narrow large head. I used a couple of extra pads in the temple areas. This fits fine. The straps seem a little awkward where they come together under the ears but I may not be fitting it right.Basically, when I ride, I forget about the helmet. Ridden in 25-115 degrees. Fits over skull caps and is cool enough on really hot rides.No wrecks (knock on wood), so I can't report on it's main purpose of protection.
